4 Claims.

This invention relates to a coping or like finishing element.

An object of the invention is to provide an improved coping or like element which may be firmly 5 secured to the top of a wall.

Another object is to provide an improved coping which will present a neat and smooth appearance. Another object is to provide an improved cop-' ing which will effectively protect the wall or the like to which it is applied.

Another object is to provide an improved coping which may be readily and economically manufactured.

Another object is to providean improved coping which will be compact and free from projecting parts.

Another object is to provide an improved coping which will be emciently secured to the wall or the like on which it is installed.

0 Another object is to provide an improved coping which may be easily and economically installed.

Another object is to provide an improved coping in which adjacent sections will be effectively secured together. g

5 Another object is to provide an improved coping which will be strong and durable.

'Other objects will hereinafter appear.

The invention will be better understood from the description of one practical embodiment ythereof, illustrated in the accompanying drawing, in which;

Figure 1 is a side elevational view of a section of brick wall having a row of coping blocks thereon;

; Figure 2 is a cross-sectional view of the wall of Figure 1;

Figure 3 is a view similar to Figure 2, showing a block in the process of being placed upon the top of the wall; a

Figure 4 is a sectional view taken on the line IV--IV of Figure 2; and

Figure 5 is a. cross-sectional view of a pair of coping blocks, showing the manner of their man ufacture.

The coping shown consists of a series of tilelike sections which may be arranged upon the top of a wall, such as a building parapet, in end to end relation, and which may be effectively sealed to the wall-top and to each other by mortar, cement or similar material.

Each section is shown as of hollow con'struc-f tion, being an integral piece of material such as baked ceramic tile, and having a slightly curved lower or contacting web I which is adapted to be positioned above and closely adjacent to the top course of brick 2.

The curvature of the web, presenting a concave surface toward these bricks, precludes any slight irregularities in the upper surface of the bricks 5 from contacting the bottom web between its edges, which might cause it to rock or tilt about such point of contact.

A central web 3 extends upwardly from the bottom web and connects it to a top 4, presenting a convex surface to the exterior of a coping block, and preferably of a greater curvature than the bottom web I.

Sides 5 connect the outer edges of the top 4 and bottom I and are continued into downwardly extending ribs 6, the inner surfaces of which converge toward each other in a direction away from the bottom I.

The ends of the coping block are of stepped formation, the bottom web I projecting a substantial distance beyond the top 4 at one end, and receding thereunder by substantially the same distance at the other end, the sides 5 above the bottom wall terminating inalinement with the edges of the top 4, while the flanges 6 are substantially coextensive with the bottom I.

The under-surface of bottom I, as well as the inner surfaces of flanges 6, may be roughened toinsure more ready adhesion of mortar or cement thereto, and, if desired, the interior of the two hollow spaces defined by the upper and lower webs, the sides, and the central web may be similarly roughened.

The coping is installed as best illustrated in Figures 2, 3, and 4.

A layer of cement I is spread upon the top of the upper course of bricks, 2, and a coping section is laid upon it and pressed down, which extrudes some of the cement into the corners of the channeled shaped recesses defined by the bottom I and ribs 6.

The coping is moved from the position shown in Figure 3,, where the extrusion of the cement has just commenced, to that shown in Figure 2, where the entire space between the bricks and the coping section bottom and between the bric and fiangesfi are filled with cement.

Cement is next applied at 9 to the end of the coping section in suflicient quantity to fill the endof the spaces I0, and the next coping section is installed as indicated in Figure 4, the cement 9 entering into the recesses III of this section also and filling the spacebetween the step-shaped ends of the two adjacent sections.

Upon the hardening of the cement, this forms effective keys projecting into the spaces III of adjacent tiles, while forming also an efficient seal between the upper walls 4 thereof, the sides 5, and the overlapping stepped ends of the side sections, this being so, even though cement may work out from between the adjacent ends of the flanges 6.

Also, the cement at 8 forms a kind of dove-tail like connection between the upper course of bricks 2 and the flanges 6, which will be tightly wedged in place by any force attempting to raise the coping sections from the bricks.

' Consequently, by the very simple operation of spreading cement on top of the wall, dropping additional amounts upon the projecting lower steps of the coping sections as successive sections are laid, and pressing the sections into place, both eflective sealing and efiective anchoring of these sectionsis obtained.

The use of the hollows l0 not only facilitates the sealing and the keying together of successive section.s,'but provides a double seal against the entrance of moisture through the coping to the wall.

The coping may conveniently be formed as indicated in Figure 5, two sections being made integrally and scored as indicated at I l to permit their readily being split apart before use.

The sections may conveniently be extrudedfrom an ordinary tube forming machine, and the step-shaped ends easily produced by cutting, without the necessity for the use of dies which have been required for the belied ends heretofore employed.

While I have described the illustrated embodiment of my invention in some particularity, obyiously many others will readily occur to those skilled in this art, and ,I do not therefore limit myself to the precise details shown and described herein, but claim as my invention all embodiments, modifications and variations coming within the scope of the appended claims.

-I claim:

1. A coping section havinga portion of generally channel-shape adapted to embrace the edge of a wall, the inner faces of the flanges of said channel-shaped portion converging in a direction away from the web thereof.

2. A' coping section comprising a generally channel-shaped unitary piece, the surface of the web of which within the recess of the channel is slightly concave, and the inner surfacesof the flanges of the channel converging in the direction away from the web thereof..

3. A coping section comprising a tile having unitary lower and upper webs connected by side and central webs, the lower web being slightly concave to the exterior of the tile, and the upper web being convex and of a greater curvature than the lower web, and depending ribs the inner surfaces of which converge in the direction away from said webs.

4. A coping comprising a plurality of tile sections, each consisting of a unitary piece of material defining spaced upper and lower webs and sides connecting said webs, the upper and lower Webs being displaced lengthwise of the section, whereby the lower web projects at one end of the piece and the upper at-the other end, the projecting ends of adjacent sections overlapping and being joined together by cementitious material spanning the space between the webs.
